Zigbee Unit

Zigbee is a self-organizing network communication module launched by M5Stack. The module adopts the CC2630F128 solution, integrates the Zigbee protocol stack internally, and provides an open serial communication interface. It features an external antenna, with a stable single-node communication distance of up to 1 km and supports up to 200 levels of router depth. Through MESH networking, it can significantly extend the range of your IoT applications, offering both ultra-low power consumption and high sensitivity. The Zigbee network can support hundreds of nodes and has enhanced security features, providing a complete and interoperable IoT solution for home and building automation.
